Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X250SCA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X250SCA is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 250mm stroke, 1/4" air ports and a SUS304 stainless-steel barrel for mildly corrosive environments. For the same bore and stroke it is shorter than an ISO 6432 cylinder, saving mounting space.

About the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X250SCA
Delivering 628.3 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles heavy-duty actuation within a compact footprint. For the same bore and stroke, the riveted SUS304 stainless barrel and aluminium cover design is notably shorter than an ISO 6432 cylinder, saving valuable machine space. The built-in CA pivot back cover provides direct rear mounting flexibility.
A defining feature is the variable air cushion at both ends; a needle valve lets you tune the deceleration to absorb high-speed end-of-stroke shock, protecting the load and reducing noise. This specific SKU includes a piston magnet (-S) for use with CMSG, DMSG or EMSG sensors. Based on the 0.5 MPa push rating, it provides a safe working load of about 377 N, meaning it lifts roughly 32 kg vertically with a 2:1 safety margin. The 1/4" port and M14x1.5 male rod thread ensure robust flow and attachment for this 40 mm bore class.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X250SCA Is Used
Heavy Carton Diversion
Pushes heavy loaded pallets at high cycle rates on a packaging line; the tuned air cushion absorbs the end-of-stroke impact to protect the 32 kg load.
Press Ejection
Ejects dense metal or plastic parts from a press bed using the full 628.3 N push force, relying on the CA pivot to accommodate angular misalignment.
Vertical Material Lowering
Lowers heavy material chutes smoothly; the adjustable needle decelerates the downward travel to prevent a hard stop, while a pilot check valve holds the load.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X250SCA the Right Cylinder?
When sizing this 40 mm bore unit, step down to an MFC32 if your load requires less than 402.2 N at 0.5 MPa, as no larger MFC bore exists for heavier demands. The variable air cushion is essential when cycling at high speeds or moving substantial masses, preventing harsh impacts at the 250 mm stroke end. Remember the cushion only decelerates the piston; it does not function as a lock or brake. If the load must be prevented from drifting when air pressure drops or the valve is centered, you must add an external rod lock or a pilot-operated check valve. Ensure you specify the -S magnet option if position feedback via CMSG, DMSG or EMSG switches is required.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/CM) & mount (LB/FA/SDB/TC)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check Use correct back cover (CA/U/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X250SCA FAQ
This 40 mm bore cylinder features a 1/4" port and an M14x1.5 male rod thread. It generates 628.3 N push and 527.8 N pull at 0.5 MPa, increasing to 879.6 N push and 738.9 N pull at 0.7 MPa. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
The -S suffix means the cylinder has a built-in piston magnet for CMSG, DMSG or EMSG sensors. It cannot hold a load on air loss; the variable air cushion only decelerates near the stroke end and is not a brake. For vertical loads, install an external rod lock or pilot check valve to prevent drifting.
